A milkman sells 81 liter milk in a town. Each of his customers buy 9 liters of milk. To increase his profit the milkman adds 9 liters of water every time he sells 9 liters milk to a customer. What is the ratio of pure milk received by the 3rd customer and water in the milkman's container before 4th sell ?

After he pours 9 liters of milk for the first customer, how many liters of milk remain? (Hint: Subtract.)

If he adds 9 liters of water to the milk, then what is the percentage of the mix that is milk? (Hint: Divide.)

After he pours 9 liters of mix for the second customer, how many liters of mix remain? (Hint: Subtract.)

Of these liters, how many are milk? (Hint: Multiply.)

If he adds 9 liters of water to the mix, then what percentage of the mix is still milk?

And so forth.

If you get stuck, please reply showing your work in doing the above steps. Thank you! ;)
